Help! Corals dying

So it has been the week from hell so why not end in a tank disaster. I had to be in Federal Court in Boston all week on a copyright infringement case my company brought starting 6 years ago. Also, my husband's business partner was killed in a workplace accident last weekend. So my attention has not been on the tank. I stayed in Boston on Monday and Tuesday nights, went home Wednesday night and noticed some of the corals looked a bit funny. But with having to go back to Boston on Thursday, then shop for black suits for the wake and funeral, then go to them on Friday and yesterday -- still no time to focus. So then Friday my huge birdsnest looked like it was dying and sure enough the whole colony -- easily 6-8 inches across is dead. My beautiful blasto -- has about half the heads dying, my ORA green birdsnest -- the tips are dying. Tri-color acro is withdrawn, acans are dying. Corals that so far look okay are all of the euphylias -- hammers, torch, frogspawn, the plates look okay, all the millis look okay. Open brain looks a bit pinched, lobos look okay, aussie elegance looks okay, most acros are withdrawn.

So, new things in the tank in the last month -- couple of corals; goni and a hammer. Couple of fish -- rescued a toadfish who is living in the sump and a leopard from Kiah was added on Thursday. The leopard did throw a bunch of sand out when she dived when first added but she is out and about and my sand bed was completely stirred up by the tennenti that was in the tank last fall. And stuff was looking funny before she was added. No new foods, same salt TM Pro (I shifted to pro from TM regular about a month ago), parameters have been stable for a month now since going to pro and adding the calcium reactor: Ca 450, Alk 9.9 and Mag 1170. I do weekly water changes of about 10% with RODI water. RODI cartridges were changed at the end of Dec. I change carbon weekly and GFO monthly and have been using the same stuff for a year at least. Light bulbs have been changed twice due to bad bulbs so cyano outbreak triggered and not gone away. Shaded the tank when added the bulbs for two weeks -- the last change was about a month ago. Water temp was 79.8 last night after the warm day -- I have a huge volume of water. I am running the biopellets and they are not tumbling a lot and yes the output is in front of the skimmer. Skimmer is running normally -- no excessive action there.

What I have done -- so far I emptied the dual BRS and filled both canisters with carbon. I have water mixing and planning on doing one water change in the morning -- I do plan on going back to sleep! I was going to do it last night but ended up having margaritas and for someone who hardly drinks ... well I fell into bed. B recommended changing water out of the actual display instead of my water changing tank. I will then mix more water and do a second water change in the afternoon.

B recommended a poly filter but I do not have one and all of the stores are closed. I do not think there was anything used such as sprays, cleaners etc as I have birds so nothing noxious is used in the house. No painting or any kind of work involving fumes have been used. The water leaks cannot affect the tanks. We have well water so the water is clean -- nothing nearby could affect it I don't think that would not get filtered by the RODI.

I am stumped.

I have a poly filter if you need it - just picked it up. Sorry to hear things are not well
 
I have a theory. I may be able to load a picture -- maybe not -- Hughes net stinks. Anyway, I have examined two corals -- a lobo and a blasto -- and found some clear filmy looking stuff with white dots in it. I am wondering if some kind of pest infested the birdsnest -- which is dead now -- and as it died it upset the rest of the corals as I did not remove it. The big load of carbon helped with that and I will do a water change today -- everything is looking better from just doing the carbon hit.

So I am thinking about dipping every coral I find with this stuff on it -- can I mix the Brightwell Aquatics coral dip with betadine? I was thinking of a double hit.

I am going to try and load the picture in a separate post.
 
Sherri, sorry to hear that you're up against a lot of stress in you life now and I hope all subsides. Take any issues with your tank one step at a time with enough time span to monitor your tank. Carbon changes is a good step as well as a water change. In my opinion to dip your corals at this stage may cause a problem since the tank is under stress that dipping may create more issues on the corals. Let them be for now and watch the corals for a few days to a week.
 
here's the picture ...

Thanks Michele for the offer but as you can see -- now I think I have a pest. Leroy -- I hear you but am thinking sooner might be much better than later given how quickly the birdsnest went.
